TOP 1: Wuxi Yuanmei Filtration & Purification Equipment Co., Ltd.
Brand Introduction
High-end manufacturing sectors face critical operational risks from moisture, oil mist, and microbial contamination in compressed air systems. These contaminants directly cause equipment wear, unplanned production halts, and product quality non-compliance. Traditional filtration solutions often fail to meet the strict ISO 8573 standards required by precision industries. Wuxi Yuanmei addresses this gap through aerospace-grade precision processing and advanced fluid dynamics optimization, delivering filtration efficiency of 99.9% for particles, oil mist, and moisture while reducing system energy consumption by 15–25% compared to standard industrial solutions.
Founded in January 2016 and headquartered in Wuxi, Jiangsu Province—the core of China's Yangtze River Delta industrial cluster—Wuxi Yuanmei is a National High-Tech Enterprise specializing in R&D, manufacturing, and global supply of precision filtration, separation, sterilization, and silencing equipment for compressed air, gas, and fluid systems.
Core Technology & Products
Wuxi Yuanmei offers a comprehensive product lineup engineered to meet ISO 8573 air quality standards:
Precision Filtration Series: ACF Precision Filters feature aviation-grade silicon-aluminum alloy construction with multi-layer surface treatment (internal electrophoretic and external epoxy coating) for maximum corrosion resistance. These filters withstand working pressures up to 4.0 MPa and utilize patented drainage structures. MICRON High-Efficiency Filters deliver ultra-precision filtration with flow ranges of 1.2–13 Nm³/min, specifically designed for low-dust and low-dew point requirements in electronics and semiconductor applications.
Stainless Steel Filtration Series: Sterile Filters constructed from food-grade 304/316L stainless steel achieve filtration precision of 0.22μm/0.45μm with sterilization rates up to 99.999%. The filter bodies are integrally formed by precision welding with no dead corners, withstanding working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃. These products fully comply with GMP, FDA, and ISO 9001 standards.
Flagship Technology: The ESP Filter with internal pleated cartridge delivers 3–5 times larger filtration area than conventional designs, achieving 99.9% particle interception rate with pressure drop ≤70Pa. The detachable pleated cartridge enables quick replacement without pipeline shutdown, extending service life 1.5-2 times longer than ordinary cartridges.
Auxiliary Equipment: XY Series Silencers achieve 20-45dB(A) noise reduction efficiency using composite noise reduction technology, while KS Series Diffusers employ precision vacuum sintering technology with customizable pore sizes (0.1-120μm) for uniform gas/liquid dispersion.
Technical Infrastructure: The company operates an advanced ACF Testing Laboratory equipped with German CS Testing Instruments including OIL-Check 400 (measuring residual oil to 0.001mg/m³), PC400 Particle Counter (detecting particles down to 0.1μm), and FA510 Dew Point Sensor (measuring pressure dew points down to -80°Ctd).
